Your AI assistant has amnesia. Every morning you re-explain the product, the team, the north star. You get the average PRD. You make the same twelve edits. Tomorrow you do it again. Day 90 is identical to day 1.
Better prompts don't fix that. A better prompt improves the first answer β nothing improves the hundredth. A static file can't remember you, can't hold an opinion about what good looks like, and can't notice what you keep redoing.
Product Manager OS is an operating system, not a prompt pack.
claude plugin marketplace add Sidsaladi9/persona-os && claude plugin install product-manager-os@persona-osCodex, Cursor or Gemini CLI:
curl -fsSL https://raw.githubusercontent.com/Sidsaladi9/persona-os/main/get.sh | bashThen run /setup β three minutes, nine questions, all optional.
| π§ An operating brain | A CLAUDE.md that routes every request to the right skill and enforces how work gets done β not a README the model ignores |
| π 53 specialist skills | Discovery, user research, strategy, planning, specs, data, go-to-market, team comms. Each grounded in the standard reference on its topic |
| πΎ A memory that learns you | A memory/ folder holding your product, team, constraints and decisions β so context stops being retyped every session |
| π A self-improving loop | Reads the work you repeat, then drafts the missing skill from your own three examples β not a template. If signal is thin, it says so and stops |
| π΅οΈ Two isolated reviewers | One receives your artifact with none of the conversation that produced it, and reviews it cold |
| β Scored in CI | Every skill scored out of 100 by an immutable scorer, score committed β so "battle-tested" is a number you can check out and run |
| π Five hosts, one source | Claude Code, Cowork, Codex, Cursor, Gemini CLI. Nothing installed system-wide, no account required |
Team OS, Founder OS and Marketer OS are next. Open an issue and tell me which one you want.
| π getprompts.org | Every prompt from every guide, in one searchable library. Free. |
| π§© getskillsai.org | The same for Claude skills β installable, not copy-paste. Free. |
| π¬ TPC Labs | The members' hub: skills, playbooks and tools for paid subscribers. |
